Description

Technical Field

[0001] The present application relates to the field of medical devices, and in particular to a respiratory control device, system, computing equipment and storage medium during anesthesia. Background Art

[0002] With the advent of comfortable medical care, not only are more and more invasive operations requiring the participation of anesthesiologists, but more and more non-invasive examinations are also inseparable from anesthesiologists, such as gastroscopy, colonoscopy or painless abortion. In recent years, the demand for anesthesia outside these operating rooms has exploded. Due to the short operation or surgery time, more anesthesiologists have chosen non-intubation general anesthesia.

[0003] Non-intubation general anesthesia refers to general anesthesia without endotracheal intubation or laryngeal mask to manage the patient's airway. This method maintains airway patency and spontaneous breathing by regulating the depth of anesthesia, prohibits the use of muscle relaxants, and accounts for the vast majority of daytime anesthesia. For example, the main method of gastroscopy anesthesia is non-intubation general anesthesia, which can reduce the adverse reactions caused by operations such as endotracheal intubation and mechanical ventilation, and is beneficial to the patient's prognosis.

[0004] In the continuity assessment of sedation depth by the American Society of Anesthesiologists, deep sedation and general anesthesia can easily lead to insufficient spontaneous breathing and interfere with airway patency. Non-intubation general anesthesia has the characteristics of retaining spontaneous breathing, and patients are prone to risks such as respiratory depression and airway obstruction. This places higher demands on airway control during anesthesia. Summary of the invention

[0073] The exemplary embodiments disclosed in the present application will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the specific embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present application and to fully convey the scope disclosed in the present application to those skilled in the art.

[0074] In the following description, a large number of specific details are given in order to provide a more thorough understanding of the present application. However, it is obvious to those skilled in the art that the present application can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present application, some technical features well known in the art are not described; that is, all features of the actual embodiments are not described here, and well-known functions and structures are not described in detail.

[0075] In order to thoroughly understand the present application, detailed steps and detailed structures will be presented in the following description to illustrate the technical solution of the present application. The preferred embodiments of the present application are described in detail below, but in addition to these detailed descriptions, the present application may also have other implementation methods.

[0076] Under anesthesia, patients are prone to "upper airway collapse". "Upper airway collapse" can be understood as "under anesthesia, the soft tissue around the patient's upper airway relaxes, and the relaxed soft tissue falls downward with gravity, causing the airway to narrow and block". When the respiratory airflow passes through the narrow part, the resistance increases, the amount of respiratory air that can pass through decreases, and the inhaled oxygen decreases accordingly. The resulting hypoxia is very dangerous. Studies have shown that the incidence of hypoxemia in grade I and II patients recognized by the American Society of Anesthesiologists (ASA) during endoscopic examinations is about 51%, and the incidence of apnea during procedural sedation and analgesia outside the operating room is about 54.2%, of which 37.8% of patients suffer from hypoxemia.

[0077] The key to airway management during non-intubation general anesthesia is to detect respiratory depression as early as possible and deal with airway obstruction in a timely manner. In the related art, by monitoring end-tidal carbon dioxide (ETCO2), observing the expansion and contraction of the air storage bag, observing the tidal changes of nasal mask exhalation, observing abdominal breathing movements (insensitive) or monitoring pulse oxygen saturation (delayed for several minutes), it is determined whether respiratory depression occurs. However, a single parameter or manual observation has the problem of inaccurate and untimely judgment, which affects the patient's personal safety. In addition, the methods of dealing with airway obstruction in the related art include jaw support, manual positive pressure ventilation, or the use of laryngeal mask and endotracheal intubation. These treatment methods, on the one hand, require more manual intervention, and on the other hand, the operation is complicated, and may hinder treatment operations such as gastroscopy. Therefore, the requirements for airway control devices during anesthesia are getting higher and higher, in order to improve the level of control of the airway during anesthesia, and thus ensure the safety and comfort of patients.

[0078] Based on this, the present application proposes the following technical solutions.

[0079] Embodiment 1

[0080] The present application embodiment provides a respiratory control device 100 during anesthesia, referring to Figure 1 , the airway control device 100 during anesthesia may include:

[0081] A first acquisition module 101 is used to acquire at least two respiratory parameters representing the patency of the respiratory tract of the target organism;

[0082] A determination module 102, for determining a comprehensive respiratory assessment value of a target organism based on at least two respiratory parameters;

[0083] The control module 103 is used to increase or decrease the intensity of electrical stimulation to the biological tissue associated with the respiratory tract according to the numerical value of the comprehensive evaluation value of the respiratory tract, so as to improve the patency of the respiratory tract.

[0084] In an embodiment of the present application, a comprehensive respiratory assessment value of the target organism is determined by at least two respiratory parameters that characterize the patency of the respiratory tract, and based on the numerical value of the comprehensive respiratory assessment value, the intensity of electrical stimulation of biological tissue associated with the respiratory tract is increased or decreased to improve the patency of the respiratory tract. This improves the level of control over the respiratory tract during anesthesia and can better ensure the safety and comfort of the target organism.

[0085] It should be noted that in the embodiments of the present application, the intensity of the electrical stimulation can be characterized by the intensity of the current applied to the electrical stimulation. Specifically, for example, by increasing or decreasing the current value of the applied electrical stimulation, the intensity of the electrical stimulation on the biological tissue associated with the respiratory tract can be increased or decreased.

[0086] In practical applications, such as Figure 2 As shown, at least two respiratory parameters characterizing the patency of the respiratory tract can be obtained by at least two of the respiratory flow sensor, nasal oxygen tube, electromyographic electrode and blood oxygen saturation sensor arranged at the corresponding parts of the target organism. Electrical stimulation can be applied to the biological tissue associated with the respiratory tract by wearing the intermediate frequency electrode under the chin of the target organism to electrically stimulate the genioglossus muscle and the hypoglossal nerve branch, so as to promote the stress contraction of the genioglossus muscle, increase the contraction tension of the respiratory tract, and thus improve the patency of the respiratory tract. In this way, the intermediate frequency electrode is worn outside the body, which is a non-invasive operation, and the operation is simple, the comfort is good, and the applicability is wide. In some other embodiments of the present application, it is not excluded to apply electrical stimulation to the biological tissue associated with the respiratory tract in other ways, such as setting the electrode in the oral cavity of the target organism to apply electrical stimulation to the biological tissue associated with the respiratory tract. In addition, the acquired respiratory parameters (such as diaphragm electromyographic value, respiratory flow, end-tidal carbon dioxide, blood oxygen saturation, etc.) and the intensity of the electrical stimulation can be displayed on the display screen to facilitate medical staff to view and control.

[0087] In some embodiments, the first acquisition module 101 may be specifically used for:

[0088] The values ​​of at least two respiratory parameters of the target organism before and after anesthesia are obtained.

[0089] In the embodiment of the present application, by obtaining the values ​​of at least two respiratory parameters of the target organism before and after anesthesia, respectively, it is convenient to use the values ​​of the at least two respiratory parameters obtained before anesthesia as a reference, combined with the values ​​of the at least two respiratory parameters obtained after anesthesia, to provide a basis for the next step of accurately evaluating the patency of the airway of the target organism after anesthesia.

[0090] It should be noted that, before anesthesia in the embodiments of the present application refers to the period before the anesthetic operation is performed on the target organism, when the target organism is awake and in a stable physical state; and after anesthesia includes the period during which the anesthetic operation is performed on the target organism, the period during which the target organism is in an anesthetic state, and the period during which the target organism recovers from anesthesia.

[0091] In some embodiments, the at least two respiratory parameters may include: diaphragm electromyography parameters and respiratory flow parameters; the first acquisition module 101 is further used to:

[0092] obtaining a first diaphragm electromyographic value and a first respiratory flow rate of the target organism before anesthesia;

[0093] obtaining a second diaphragm myoelectric value and a second respiratory flow rate of the target organism after anesthesia;

[0094] The first diaphragm electromyographic value and the second diaphragm electromyographic value are respectively measured values ​​of diaphragm electromyographic parameters, and the first respiratory flow and the second respiratory flow are respectively measured values ​​of respiratory flow parameters.

[0095] The diaphragm is the most important respiratory muscle of the respiratory system. The inhalation and exhalation of gas rely on the work of the diaphragm to form positive and negative pressures in the alveoli, thereby forming breathing. Therefore, measuring the diaphragm electromyographic parameters can directly and accurately reflect the real respiratory drive and respiratory load of the target object. In this embodiment, by obtaining the diaphragm electromyographic parameters and the respiratory flow parameters, the degree of patency of the airway of the target organism can be reflected very timely and accurately, thereby providing a basis for obtaining a more accurate comprehensive evaluation value of the respiratory tract in the future. In addition, the respiratory resistance value can be further obtained according to the numerical values ​​of the diaphragm electromyographic parameters and the numerical values ​​of the respiratory flow parameters. For the specific method of obtaining the respiratory resistance value, please refer to the introduction below. In some other embodiments of the present application, it is not excluded that the respiratory parameters include other physiological parameters, such as blood oxygen saturation, respiratory rate or end-tidal carbon dioxide.

[0096] Exemplarily, surface electromyographic electrodes can be used to collect diaphragm electromyographic signals to obtain the values ​​of diaphragm electromyographic parameters. In practical applications, if diaphragm electromyographic detection is used, the respiratory rate can also be detected. The method of obtaining respiratory parameters may include, for example, at least one of impedance respiratory detection, temperature and / or humidity detection, airflow detection, etc. Among them, the operating forms of different respiratory detection methods may also be different. For example, for impedance respiratory detection, electrodes need to be attached; for temperature and / or humidity detection, it needs to be placed in the nostrils, and a temperature and humidity sensor or a temperature sensor or a humidity sensor can be used; for airflow detection, it also needs to be placed in the nostrils. Optionally, the respiratory signal can be obtained by temperature detection. Specifically, a fast-response thermistor is used as a temperature sensor and placed in the nose, which is easy to use and low in cost.

[0097] In the embodiment of the present application, the first diaphragm EMG value and the first respiratory flow before anesthesia can be recorded as EMG0 and F0, respectively, and the second diaphragm EMG value and the second respiratory flow after anesthesia can be recorded as EMGx and Fx, respectively.

[0098] In some embodiments, the first acquisition module 101 may also be used to:

[0099] Acquire a first respiratory resistance value and a second respiratory resistance value;

[0100] The first respiratory resistance value is the ratio of the first respiratory flow rate to the first diaphragm myoelectric value; the second respiratory resistance value is the ratio of the second respiratory flow rate to the second diaphragm myoelectric value.

[0101] In the embodiment of the present application, the respiratory resistance value is obtained by the ratio of the respiratory flow and the diaphragm electromyography value. For example, when the airway is not patency is poor, the respiratory flow will decrease, and the diaphragm will increase the respiratory driving force, causing the diaphragm electromyography value to increase. At this time, the respiratory resistance value is smaller. Therefore, the respiratory resistance value can more comprehensively reflect the patency of the target organism's respiratory tract, and then reflect whether the target organism's respiratory state is good.

[0102] In the embodiment of the present application, the first respiratory resistance value may be recorded as L0, where L0=F0 / EMG0, and the second respiratory resistance value may be recorded as Lx, where Lx=Fx / EMGx.

[0103] In some embodiments, the determination module 102 may be specifically configured to:

[0104] normalizing the second respiratory flow to obtain a first intermediate parameter;

[0105] Normalizing the second respiratory resistance value to obtain a second intermediate parameter;

[0106] The first intermediate parameter and the second intermediate parameter are assigned different weights and then added to determine a comprehensive respiratory tract assessment value.

[0107] In the embodiment of the present application, by normalizing the second respiratory flow Fx and the second respiratory resistance value Lx to obtain the first intermediate parameter and the second intermediate parameter, the difference in dimension and unit between the second respiratory flow Fx and the second respiratory resistance value Lx can be removed, so that different parameters have better comparability. Further, by assigning different weights to the first intermediate parameter and the second intermediate parameter and then accumulating them to obtain a comprehensive respiratory evaluation value, the comprehensive respiratory evaluation value obtained in this way can more comprehensively and accurately reflect the patency of the respiratory tract, thereby improving the management level and reliability of the device.

[0108] The following example uses the maximum-minimum normalization method to normalize the second respiratory flow Fx and the second respiratory resistance value Lx. It can be understood that in some other embodiments of the present application, other normalization methods, such as standard deviation normalization, are not excluded for normalizing the second respiratory flow and the second respiratory resistance value.

[0109] In some embodiments, the determination module 102 may also be used to:

[0110] Determine a minimum respiratory flow rate and a maximum respiratory flow rate according to the first respiratory flow rate;

[0111] determining a first difference between the second respiratory flow and the minimum respiratory flow;

[0112] determining a second difference between the maximum respiratory flow and the minimum respiratory flow;

[0113] The first difference is divided by the second difference to perform normalization processing to obtain a first intermediate parameter.

[0114] In some specific embodiments, the determination module 102 can also be used to multiply the first respiratory flow F0 by the first coefficient a1 to obtain the maximum respiratory flow Fmax, and multiply the first respiratory flow F0 by the second coefficient a2 to obtain the minimum respiratory flow Fmin; the first coefficient a1 is 0.5-1.2, and the second coefficient a2 is 0.3-0.8; the maximum respiratory flow Fmax is greater than the minimum respiratory flow Fmin.

[0115] In the embodiment of the present application, the first intermediate parameter can be recorded as Fn, where Fn=((Fx-Fmin) / (Fmax-Fmin))*100.

[0116] In some embodiments, the determination module 102 may also be used to:

[0117] Determine a minimum respiratory resistance value and a maximum respiratory resistance value according to the first respiratory resistance value;

[0118] determining a third difference between the second breathing resistance value and the minimum breathing resistance value;

[0119] determining a fourth difference between the maximum breathing resistance value and the minimum breathing resistance value;

[0120] The third difference value is divided by the fourth difference value to perform normalization processing to obtain a second intermediate parameter.

[0121] In some specific embodiments, the determination module 102 can also be used to multiply the first breathing resistance value L0 by the third coefficient b1 to obtain the maximum breathing resistance value Lmax, and multiply the first breathing resistance value L0 by the fourth coefficient b2 to obtain the minimum breathing resistance value Lmin; the third coefficient b1 is 0.5-1.2, and the fourth coefficient b2 is 0.3-0.8; the maximum breathing resistance value Lmax is greater than the minimum breathing resistance value Lmin.

[0122] In the embodiment of the present application, the second intermediate parameter can be recorded as Ln, where Ln=((Lx-Lmin) / (Lmax-Lmin))*100.

[0123] In the embodiments of the present application, the comprehensive respiratory evaluation value can be recorded as Q. In some specific embodiments, Q = k1*Fn+k2*Ln, where k1+k2 = 1. Optionally, k1 is 0.3-0.7, and k2 is 0.3-0.7, so that the obtained comprehensive respiratory evaluation value Q can better balance the weights of respiratory flow and respiratory resistance values ​​and reduce errors.

[0124] It should be noted that the comprehensive respiratory assessment value Q ranges from 0 to 100. When the calculated Q value is greater than 100, the Q value is 100.

[0125] In some embodiments, the control module 103 may be specifically used to:

[0126] When the comprehensive respiratory tract assessment value is less than or equal to the first preset value, the intensity of electrical stimulation is controlled to increase; when the comprehensive respiratory tract assessment value is greater than or equal to the second preset value, the intensity of electrical stimulation is controlled to decrease; otherwise, the intensity of electrical stimulation is kept unchanged.

[0127] In the embodiment of the present application, the intensity of the electrical stimulation can be adaptively adjusted by the comprehensive respiratory evaluation value Q to control the intensity of the electrical stimulation within an appropriate range. In this way, on the one hand, the respiratory tract of the target organism can be kept in a relatively good state of patency, and on the other hand, discomfort to the target organism caused by a large degree of opening of the respiratory tract can be avoided, that is, comfort can be guaranteed while ensuring safety.

[0128] Specifically, the first preset value and the second preset value can be set in combination with clinical data and physical parameters of the target organism, etc. In some specific embodiments, the first preset value is greater than or equal to 60, and the second preset value is greater than or equal to 80 and less than or equal to 90.

[0129] Optionally, the first preset value is 60 and the second preset value is 80. In this case, when the comprehensive respiratory tract evaluation value Q is less than or equal to 60, indicating that the target organism's respiratory tract is less open, the intensity of the electrical stimulation is controlled to increase the degree of opening of the respiratory tract and ensure better patency of the respiratory tract; when the comprehensive respiratory tract evaluation value Q is greater than or equal to 80, indicating that the target organism's respiratory tract is more open, the intensity of the electrical stimulation is controlled to be reduced to avoid discomfort to the target organism due to excessive opening of the respiratory tract; when the comprehensive respiratory tract evaluation value Q is between 60-80 (excluding the endpoint value), it indicates that the target organism's respiratory tract is within an appropriate range and the intensity of the electrical stimulation can be kept unchanged.

[0130] In some other embodiments of the present application, it is not excluded that the intensity of electrical stimulation can be manually adjusted according to the comprehensive respiratory tract assessment value.

[0131] In some embodiments, please refer to Figure 3 The airway control device 100 during anesthesia may also include:

[0132] The second acquisition module 104 is used to acquire at least one monitoring parameter of the target biological body; the at least one monitoring parameter includes end-tidal carbon dioxide (ETCO2) and / or blood oxygen saturation (SpO2).

[0133] Both end-tidal carbon dioxide and blood oxygen saturation can characterize the vital signs of the target organism. In the embodiment of the present application, the safety of the target organism can be monitored by monitoring the values ​​of end-tidal carbon dioxide and / or blood oxygen saturation. In particular, after the intensity of the applied electrical stimulation is adjusted, the synchronous monitoring of the values ​​of ETCO2 and / or SpO2 can provide comprehensive feedback on the state of the target organism, thereby better ensuring the safety of the target organism.

[0134] In some embodiments, please refer to Figure 4 The airway control device 100 during anesthesia may also include:

[0135] The monitoring module 105 is used to issue an alarm message when it is detected that at least one monitoring parameter exceeds a preset range.

[0136] In an embodiment of the present application, when at least one monitoring parameter (such as ETCO2 and / or SpO2) is monitored to be outside a preset range, it indicates that the target organism may be in a dangerous state such as hypoxia. In particular, after adjusting the intensity of the electrical stimulation, if the patency of the respiratory tract still cannot be improved, causing the values ​​of ETCO2 and / or SpO2 to exceed the preset range, an alarm message can be issued to facilitate medical staff to know at the first time that the target organism is in danger, so as to intervene in time to ensure the safety of the target organism.

[0137] In some embodiments, the monitoring module 105 may also be configured to, in the step of controlling the increase in the intensity of electrical stimulation, issue an alarm message if it is monitored that the intensity of electrical stimulation has increased to a maximum value.

[0138] In an embodiment of the present application, if the comprehensive respiratory assessment value is less than or equal to the first preset value and the electrical stimulation intensity needs to be increased, if it is monitored that the electrical stimulation intensity has increased to the maximum value of the relevant equipment, an alarm message can be issued to facilitate medical staff to discover and deal with it in time, thereby better ensuring the reliability of the device and the safety of the target organism.
